Bakgrund: Sömn är ett mänskligt grundläggande behov och bör därför tillgodoses hos patienter som vårdas på sjukhus. Patienter som vårdas på intensivvårdsavdelningar upplever dock ofta upprepade avbrott på sömnen och sömnbrist vilket kan leda till både fysiska och psykiska negativa konsekvenser. Intensivvårdsmiljön med dess oljud, starka belysning och frekventa vårdrelaterade interaktioner leder ofta till oförmåga hos patienterna att få en adekvat sömn. Syfte: Att belysa olika interventioner sjuksköterskan kan tillämpa för att förbättra sovmiljön och sömnkvaliteten hos patienter som vårdas på en intensivvårdsavdelning. Metod: En litteraturöversikt med grund i analys av kvantitativ forskning.

Background: First Line Managers are expected to create a health promoting work environment. Research has shown that the prerequisites for accomplishing a health promoting leadership are not always the best. Aim: The aim was to elucidate the prerequisites for a health promoting leadership as First Line Manager at a University hospital in Sweden based on competence, role, support structures and own durability. Results: First Line Managers at the chosen hospital seems to have rather good conditions for conducting a health promoting leadership. All respondents did have a university degree and most thought that their competence corresponded well with the role.

The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.

Bakgrund: Den psykiska ohälsan är ett folkhälsoproblem som sträcker sig genom alla åldersgrupper. Psykisk ohälsa är som störst bland unga mellan 16-24 år där problem med sömnen är en del av det psykiska välbefinnandet.Syfte: Syftet med studien var att undersöka studenters upplevelse av vad som påverkar sömnvanor vid högre studier.Metod: Det genomfördes intervjuer med sex stycken studerande i åldrarna 20-30 år på en högskola i sydvästra Sverige. Intervjuerna spelades in, transkriberades ordagrant och sedan analyserades dem. Analysmetod som valdes var temaanalys där tre stycken teman framkom. Hänsyn togs till de etiska aspekterna och även informerat samtycke av deltagarna.

Sömnstörningar hos ungdomar anses vara ett växande problem. Det finns misstankar om att ungdomarnas ökade användning av Informations- och Kommunikationsteknik (IKT) är boven i dramat. Ungdomar upplevs spendera en allt större del av sin tid framför datorn, samtidigt som mobilen går varm av samtal och SMS. Det saknas dock utförlig forskning kring sambanden mellan IKT-användande och sömn. Syfte: Att undersöka huruvida ungdomar lider av sömnstörningar och om det i så fall kan kopplas till deras IKT-användande.

Syfte och frågeställningar: Syftet med denna uppsats var att kartlägga sömnvanor hos kontorsarbetande, samt att undersöka vilka omständigheter som kan ligga bakom att individer sover som de gör. Vi vill tydliggöra att sömn har en stor effekt på hur vi mår och visa på vilka bakomliggande faktorer som kan förändras för att förbättra en dålig sömn.Metod: Vi har valt att använda oss av en kvantitativ metod bestående av en enkätundersökning. För den teoretiska bakgrunden har en litteratursökning genomförts och studerats. Enkäten är baserad på Karolinska Sleep Questionnaire (KSQ), där vi lagt till ett antal egna frågor. Frågorna speglar frågeställningarna för arbetet och tillhör tre olika kategorier; orsaker till sömnvanor, vanor runt sömn och övriga frågor.

Bakgrund. Miljön på intensivvårdsavdelningen är fylld av olika stimuli i form av ljud och ljus. Sjuksköterskorna arbetar bedside och täta omvårdnadsåtgärder är nödvändiga för dessa kritiskt sjuka patienter. Denna miljö lämnar en liten möjlighet för sömn och vila. För att patienterna ska få möjlighet till vila under dagtid har vissa intensivvårdsavdelningar lagt in en period med mindre aktivitet, tysta timmen, också kallat patientvila.

Chiari type I malformation is a condition in humans characterized by a small posterior cranial fossa, downward herniation of the cerebellar tonsils, foramen magnum overcrowding and disturbances of cerebrospinal fluid dynamics. Syringohydromyelia is often seen in patients with Chiari type I malformation. Syringohydromyelia is characterized by fluid-filled cavities in the spinal cord. This causes damage to the nervous tissue in the spinal cord. In recent years, a condition similar to Chiari type I malformation has been recognized in dogs. It has mostly been seen in Cavalier King Charles spaniels (CKCS). The condition seen in dogs is usually called occipital bone hypoplasia. The aim of the study was to examine whether there is a difference in the shape of the caudal fossa between CKCS, small bred dogs with a similar head shape and dogs with a normal head shape and if occipital bone hypoplasia is related to a head shape with a steep back of the head. Other aims of the study were to examine the crowding of nervous tissue in the foramen magnum in each breed group, the extent of syringohydromyelia and to what extent the malformation had caused neurological signs. Sculls from dogs on autopsy were divided in halves and the position of the cerebellum compared to the level of the foramen magnum was studied.

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Patienter som vårdas på intensivvårdsavdelningar får inte den sömn de behöver.Medelpatienten sover endast två timmar per dygn och hamnar aldrig i djupsömn eller REMsömn som kroppen så väl behöver för återhämtning och läkning. Konsekvenserna av uteblivensömn är många och en av de vanligaste följderna är IVA-syndrom. IVA-syndrom, som ocksåkallas delirium, drabbar 80 % av alla intensivvårdspatienter och är en akut psykisk förvirrig avfluktuerande grad. IVA-syndrom leder till förlängd vårdtid, ökade komplikationer ochförsämrad prognos samt minskad 6-månads överlevnad. Syftet med studien är att med hjälp aven litteraturstudie kartlägga det aktuella forskningsläget om sömn hos intensivvårdspatienteroch olika metoder att mäta och skatta sömn med fokus på omvårdnad.

Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.

Aim and scientific issuesThe aim was to identify potential health risks, for full-time working parents with small children, caused by time shortage. The intention was to better understand and help this particularly time-pressured group in society to achieve a healthier lifestyle. The identification was built upon their own opinions about possible health risks and upon an interpretation of the health risks from a health promoter?s perspective.How do full-time working parents with young children handle time-shortage in a health perspective, specified in the categories: sleep, recovery, nutrition, physical activity, social health and mental health?What consequences for health does time?shortage have for full-time working parents with young children?What do parents with young children think could help them to obtain a better health in everyday life? MethodThe study was based on a literature overview and semi-structured interviews with 6 people who were strategically selected: the interview objects were all full-time working or studying, had one child under 7 and lived together with a partner. All interviews were recorded using two dictaphones and were implemented, transcribed and analyzed by both writers of this essay to increase the reliability of the results.ResultsTime shortage is shown to be handled especially through priorities in the respondent?s lives.
